には、レンズ枠４はこれと一緒に回転せず直進だ
けする。 Also, if the push button 10 of the macro ring 3 is pressed to release the engagement with the lens barrel 1 and the macro ring 3 is rotated relative to the lens barrel 1 in the direction of the arrow in FIG. 4, the inner surface of the rear end of the macro ring 3 The lens frame 4 that is screwed into the moving frame 5, the cam cylinder 7, the operating ring 2, and the front frame
and each lens group L 1 , L 2 , with the rear lens frame 8
It is possible to move to the left in FIG. 1 and enter the macro photography area without changing the distance between L 3 and L 4 . In this case, a slit is provided at the rear end of the lens frame 4, and a protruding piece of the lens barrel 1 is inserted into the slit as shown in FIG.
When a is engaged and the macro ring 3 is rotated, the lens frame 4 does not rotate together with it and only moves straight.
ところで、操作環２のカメラ側周縁の適所に指
標１４が打刻されており、マクロリング３の外周
面には該指標１４によつて第３図ｂのようにマク
ロ域の撮影倍率を表示する軌跡線１５を画くので
あるが、それは次のように画かれる。 Incidentally, an index 14 is engraved at a suitable location on the camera-side periphery of the operation ring 2, and on the outer peripheral surface of the macro ring 3, the imaging magnification of the macro area is displayed by the index 14 as shown in FIG. 3b. The trajectory line 15 is drawn as follows.

６を刻設する。 When the macro ring 3 continues to rotate in this state and the maximum imaging magnification obtained by the built-in optical system lens group becomes, for example, 1/4, the index 14 on the operating ring 2 will change as shown in Figure 3a. Plot the point on the macro ring 3 to indicate, draw a lead line 15' from there in the optical axis direction, and mark the scale 1 with a magnification of 1:4 at the base end of the lead line 15'.
6 is carved.
次に操作環２を光軸方向左方に移動し、所望の
撮影倍率例えば1/5，1/6，1/7倍の位置ごとに指
標１４が示す点を第３図ｂのようにプロツトす
る。 Next, move the operating ring 2 to the left in the direction of the optical axis, and plot the points indicated by the index 14 at each position of the desired imaging magnification, for example, 1/5, 1/6, or 1/7, as shown in Figure 3b. do.

する。 Next, the operating ring 2 is returned to the position shown in Fig. 3a, and the macro ring 3 is rotated in the direction of the dotted line arrow (in the figure, the operating ring 2 is rotated for convenience), and the macro ring 3 is rotated as desired. When the photographing magnification reaches, for example, 1/5, plot the point indicated by the index 14 on the operating ring 2, and draw the lead line 1 from there in the direction of the optical axis as before.
5' and engrave a scale 16 with a magnification of 1:5.

ときのマクロ撮影倍率を知ることができる。 To use it, set the operating ring 2 to the closest position at a normal distance as shown in Fig. 4, press the push button 10 to disengage the lens barrel 1 and the macro ring 3, and then set the operating ring 2 to the position shown in Fig. 3a. Rotate to the macro photography area as shown,
While looking through the viewfinder, move the operation ring 2 in the direction of the optical axis to focus, and at that position move the index 14.
By reading the scale 16 of the trajectory line 15 indicated by , the macro photography magnification at that time can be known.

が簡単で使用上甚だ便利なものである。 As described above, according to this invention, when performing macro photography, it is possible to easily know at what magnification the photograph will be taken relative to the size of the subject, and,
When taking macro shots, set the operating ring to the closest position at a normal distance, press the push button on the quick stop device to disengage the macro ring from the lens barrel, and rotate the macro ring to enter the macro shooting area. , so there is no need to worry about entering the macro range due to careless rotation of the operating ring, and it is possible to reliably prevent erroneous operation. Also, during macro photography, the rotation of the macro ring allows the trajectory line of the macro magnification and its The scale is now located within the visible range, and the main reference line, focus scale, depth display line, or infrared display line used during normal shooting are set almost on the opposite side of the macro ring's outer circumferential surface. There is no fear of confusion with the normal scale mentioned above during macro photography, and the structure is simple and extremely convenient to use.
